I have used a command like the below with success in the past:
$ ffmpeg -i avfile.mkv -i srtfile.srt -i metadata.txt \
-map 0:0 -map 0:1 -map 1 -map_metadata 2 \
-c:v libx264 [ various options ] \
-c:a copy \
-c:s srt \
-c:d copy \
out.mkv
Maybe something like that will work for you.

Howdy,
I need to start with a movie file that has audio and video, and to
reencode the video and add subtitles and chapter markers.
I can add the chapters in a first pass, and then add the subtitles in a
second pass, and that works fine. But I can't seem to find the right
command to add subtitles and chapters in one pass.
For example, here is a sequence that does work:
$ ffmpeg -i avfile.mkv -i metadata.txt \
-map 0:v -map 0:a -map_metadata 1 \
-c:v libx264 [ various options ] \
-c:a copy \
temp.mkv
$ ffmpeg -i temp.mkv -i srtfile.srt \
-map 0:v -map 0:a -map 1:s \
-c:v copy \
-c:a copy \
-c:s srt \
out.mkv
However, I would like to skip the intermediate file. Here is the
command I am trying which does *not* work:
$ ffmpeg -i avfile.mkv -i srtfile.srt -i metadata.txt \
-map 0:v -map 0:a -map 1:s -map_metadata 2 \
-c:v libx264 [ various options ] \
-c:a copy \
-c:s srt \
out.mkv
Can anyone tell me a command that will work, and hopefully explain what
I have wrong?
Thanks!
